Wolf, a Democrat and former state Revenue Secretary, spoke to small business owners downtown. Corbett is a Republican. The general election is Nov. 4.

"Millionaire Secretary Tom Wolf's only interest in small businesses is raising taxes on them and their employees to pay for his big spending agenda," said Billy Pitman, press secretary for Tom Corbett for Governor. "Whether it's energy taxes, personal income taxes, electricity or garbage taxes, Secretary Wolf has never seen a tax increase he didn't like, and is unable to shake an affinity for the old tax-and-spend culture in Harrisburg that left a $4.2 billion budget deficit and unemployment as high as 8.7 percent, while Wolf's own company bailed for Delaware to pay less. It's hypocrisy at its finest."
